A frame 2| comprises a housing 22 which is of general annular form, and legs 23 depending therefrom. Three of these legs are shown arranged so as to provide a clear space 24 under the housing for the introduction of a receptacle 25 for receiving the cut material and for providing spaces 26 between the legs of the machine through which the receptacle may be'rolled 'or otherwise introduced into position for receiving l '65' secured in spaced relation thereon so as to the cut material from an inner discharge.

A supplemental frame 28 is located in the main4 frame and a bowl 29 is rotatable on the supple-` mental frame. 'Ihe supplementalfrarne is shown intermediate between the main frame land the@ bowl. 'I'he bowl is provided with a trough 30 for the meat, the bowl andthe trough being?VA shown annular. The bowl is provided with .a

worm ring gear 3|, shown formed separately from Athe-bowl: and rigidlysecuredthereto by bolts132.

A worm 35 meshes with thering gear-and is mounted on Ia shaft 36 journaled in bearings 31, 38 inthe housing v22 andina bearing. 39 on-a bracket-.40 secured to; a `coverq4| -by bolts 42 .y jr'lhe bear-ings 31,. 38for the. worml shaft are shown as solid bearings in a rearwardly extend# .ingbulge 45 o f the housing 22. The wormgis locatedand held endwise between theends of said bearings in1 a cavity 46'of said `bulge,f thecavity being provided with a1 rear'opening A||;|` vnormally closed by a removable plate 48, the worm being insertiblefintovand removable from said cavity when assembling and dismantling the structure. The worm yshaft hasga reduced inner end 149 4which is journaled in lthefbearing 38, which is of less` diameter thanthe 'bores of the bearings 31 and 39, and which is also received in the bore of :the wor1n'35,.the freduced end of said 'shaftfin said Alas't -riamedbore being providedwit-h, a key 58 received in a groove in the wall of 'saidbore to. form driving'connection with-said worm. VThe portion-,ofthe shaft in thejbearing v3`| hasya radius as-great as the 'radiusbetween'the axis ofl -said shaft and the 'outer face of said key, vso that ythe shaft may be -slid endwise; outwardly out of said Worrnand `outof its bearings for disassemblingthe parts-,fand may be inserted 'there- .into for assembling the parts, the -worm being a .shoulder 54 between the reduced endj'of the shaft and its portion of greater diameter. A positioningcoll-ar 55 is releasably secured .toisaid yshaftg. anol abuts` the inner end of the bearing 39 in order to operatively positionythe shaft andthe .worm en dwise." Aspacingfcollar 52 is located about the shaft between the worm andthe' bearing; .31, the spacing collars l53,152 positioning the worm endwisebetween the bearings 31,'v38.- YThe .cavity A46.y forms a lubricant reservoir i to'j supply thelworrnwith grease, 'j

The cover 4| is locatedfover-therear portionof; the :bowh Itslateral portions are secured to upward eXtensi-onsi of the rear'legs 'ofv the frame by `r bolts5'|, and fits rearportion is -supportedon 4ay bracket 581extending'upwardly 'from-the bulge45;

ofthe 'main frame.' torwhichthe bracket is's'ecured by bolts 59, the rear portion of the cover being secured to. this bracket.

The cover is provided with a tunnel 6 I, in which a cutter shaft 62 is located, the cutter shaft being journaled in bearings 63, 64 shown as oppositely presented taper roller bearings, the inner and outer raceways of which are respectively endwise positioned on rsaidshaft and in said tunnel, suitable vadjustable means being provided for endw'isepo'sitioning in said'bearings (Figs. 5 and 12).

This cutter shaft has a series of cutter blades 'rotatetherewitn as by having each of the cutter blades provided with a slot 66, the walls of which slots are received in opposite grooves 61 in the cutter shaft, the bottoms of the grooves and the walls of the 'slots coacting to securely position the blades-angularly on the cutter shaft, successive .bladesbeing positioned at progressive angles about the shaft. A thrust collar 68 is located at one end ofthe: series of blades by a bushing 68 .contacting a vshoulder 69 on saidl shaft. yA clamp collar lvisvlocated at the other. end of the blades, 4and spacing collars are located-between the blades. The clamp collar'is 'screwed over: the threaded inner end ofthe cutter shaft for clamping .the blades to said.` shaft. The grooves 6`| are vsubstantially Wider than the walls of the, slots 66 for permitting such clamping. The cutter shaft has an overhanging end overhanging the cover and the frame, to which a pulley-'l5 is secured. s g f A' motor supporting platev 16 is adjustably mounted von one end of the covenand has an electric motor secured thereto-(Figsl, 8. and '11). The rollery shaft'l of thernotor has a pulley '|9 secured-thereto which overhangs the coverv and the frame. Flexible driving connece tions 80, as a -V belt drive are received aboutgthe pulleys 15,19 for drivingthe cutter shaft.r The plate v|6is adjusted up and down whereby to tensionthe exible driving 'connections for proper;

driving contact ywith their pulleys.y vThe plate isv shown pivoted to the cover on a pivot rod 3| in bearings 82 on the cover, the motor supporting' plate having bearings 83 about: the 'pivot rod.: Adjusting bolts 84 are threaded in threaded lugs 85 on the cover and havegjam nuts 86 about them for securing the bolts in adjusted positions, the adjustable end of thermotorsupporting plate rest.- ing von said bolts. f

'I'he overhanging end of the cutter shaftfhas a f opening, and the bays accommodate the securing means on saidshaft for the respective ends'of 'the set ofblades '(Figs.-1,f2, 3, 4 and 5). z

A comb |0| is received in said opening, the

comb havingwider endv tongues |02, '|03' at the respective ends ofA said set of blades and intermediate narrower. tongues |04 received in the spaces 4between neiglfiboring-blades.V The-combv has a-4 base -|05-whichr is locatedyin` ashallow extensionwlbf 4th'efopening95, said extension` having a bottom |01 on whichthe baseof the comb is supported.' The `saidopening"and its'e'xtension haveside wallsv |08;A |09, betweenfwhich theA 'respectivferids of the*v comb are positioned and 'guided'. .Acombcap Al |f| is received 'over` the.'

comb, bolts ||2 yextending through holes in said capand registering holes inthe sidewalls of said shallow extension |95 and in registering holes in laterally extending lugs in the bracket 58, nuts .E |3 beingv received over the ythreaded ends of said bolts for clamping the .combv cap to the cover and clamping the rear portion of the coverto .the frame, the comb having a sliding fit in the channel thus formed at the rear end of the transverse. opening in the cover. -A bolt i5 is threaded v in the comb cap and is provided with a handle 'and is mounted so as to be moved out of the way of the blades for inspection and attention to 4the blades and the operative mechanism in association ktherewith if desired. The hood is shown hinged to the cap plate by a hinge pin-|25 in a bearing |26 on the cap plate and in bearings in rearwardly projecting lugsl |21 projecting rearwardlyy from the hood at the respective ends of the bearing 25 for laterally positioning the hood. The hinge pin is provided with a handle |28 for its ready removal and'with a lcotter pin |29 for holding the same in place.

"Hood clamps |3| having handles |32 are ypivhood on shoulder bolts |34 threaded into lugs in the cover, the clamping fingers of the clampsr having cam faces received yover laterally extending lugs |35 on the respective sides ofv the hood. The hood is provided with a handle |36 by means of which to raise and lower the same.V

v f All lower edges of the hood are tightly clamped against the cover for providing tight joints H8 therewith to preventr the escape ofv meat and meat juices therethrough, providing an inner overhanging end of the cutter shaft permitting this arrangement at said end, whereby a closed end wall I9 is presented `toward the overhanffing end of the cutter shaft and cutters (Figs. 1, 3, 5 and 12).

The inner end of the cutter shaft is provided with means to lock the same in non-rotative position when it is desired'to clamp the cutters on the shaft and'for other purposes (Figs. 11a, 11b and l2), and such means are arranged in such manner as to provide an obstruction to closingy of the hood when such means are Vin operative position, such means being further arranged to be moved out of such obstructing position -when releasing the cutter shaft.

Thus the end of the cutter shaft is formed cross-sectionally at |20 to receive an obstructing part, being shown square in cross-section and arranged to receive a wrench 24 thereover. The wrench has a correspondingly formed part, shown as a vrecess i3!) having angular walls to engage the angular walls of the end of the shaft, the recess being open at one side to allow the wrench to be slipped over the end of the shaft in lateral direction. I f

The wrench is also provided with shoulders |33 which engage the upper faces of the opposite walls |31 of the bay 96,'into which latter the end of the cutter shaftextends. Italso has end shoulders |38 which engage the innerV faces of said opposite'walls, the shoulders |33, |38 being arranged to locate the wrench and prevent its being turned. The wrench is also provided with an upwardly extending handle |39. The walls of the recess |30 extend endwise, the extreme ends thereof engaging the end wall ||9 of the bay v96, and the wrench is provided with a pin |49 rigid therein which engages the end of the cutter shaft, to position the wrench and the cutter shaft endwise.

The wrench when in position to hold the shaft is an `obstruction to the closing of the cover, as shown' in Fig. 11b, so that the operator must first remove the wrench'before he can close the cover, which latter is a prerequisite to starting the machine, thus avoiding accident.

It will be noted that the cover is provided with rearwardly extending recesses MI, |42 at its forward edge in order to expose as much as possible of the trough of the bowl to view (Figs. l and l2). The cover is provided with a lower face or web |43 to confine the material in the trough of the bowl while being fed past the. cutters, there being preferably confining joints lfllelv and M5 respectively between the outer and innerperipheral edges of the bowl and the bottom wall of said cover, in order to prevent the oozing of the meat and meat'juices out of the bowl. The infeeding transverse edge of the cover is provided with a forwardly and upwardly extending flange |46 bulged inwardly toward the middle of the trough for directing any heaped material in the bowl under the cover.

Suitable scrapers secured to the cover and to tbe frame may project into the trough for releasing adhering meat from the walls of the trough and for directing the meat laterally in the trough for operation thereon. Such scrapers are usual and are not shown.

The direction of rotation of the cutters is shown by the arrow a and the direction of rotation of the bowl is shown by the arrow b.

The theory of the cutting action of the rotating cutters on the meat in the bowl is that the cutters act on the meat in the trough as the trough with the meat therein moves under the cutters, the regular angular progression of the positioning of the blades aiding in such feeding movement. It has been found, however, that there is a tendency for the meat to be arrested or slowed in its feeding movement and to form a rotating body or masses at the infeeding end ofthe set of cutter blades and for the meat to roll in the bowl in advance of the blades at the forward or infeeding side of the comb. In order to relieve or counteract in whole or in part such rolling` or swirling of the material and to aid in the feeding movement thereof with the bowl, I have provided means whereby a space is formed at the infeeding side of the comb in to which the outer enveloping part of the revolving or swirling bodies or masses of the meat may be pinched to thereby form a brake upon such rotation or swirling of the bodies or lumps of meat, and to cause a feeding friction between the bowl and the meaty transverse opening .95 and its shallow extension |06, and between the bottom of said hollow extension and the comb cap I I (Figs. 1, 2, B and 4). The movable tongue is provided with a handle |49 for manipulation of the same. It has a laterally extending wing |50 received in .a rabbet 5| in the base of the comb and has a guide rod |52 extending inwardly from said wing, the guide rody being slidable in a bearing |53 in the downwardly extending rear wall |54 of the base of the comb. Its rear end is shown threaded in the wing |50, a limiting collar |55, adjustably secured to the guide rod, limiting the outward movement of the movable tongue.

The tongue may be moved outwardly to desirable extent, depending on the character, solidity and moisture 'content of the meat and its tendency to roll or lag in'its feeding movement. The tongue automatically remains in any desired position in which it is placed. As soon as proper feeding action of the meat has again begun, the v tongue may be moved forwardly to its normal position.

The inner end of the comb is provided with a locating pin |56 in the end of one of its tongues which contacts with one of the collars on the cutter shaft, these collars preferably having outer cylindrical peripheries so that rotation of the collar with relation to the pin is not detrimental, the clamping of the clamp bolt |5 for the comb, however, positioning the comb preferably in such manner that the inner end of the locating pin is relieved of direct contact with its positioning collar. f

The annular trough of the bowl is shown surrounding a central opening |6| to form an inner discharge for the trough. The wall of the opening is extended as a depending wall |62, to direct the discharge from the trough (Figs. l, 5 and 6).

In the form shown the trough is provided with an outer peripheral rim |63 and an inner peripheral rim |54, and means are provided for discharging the cut meat either inwardly or outwardly from the trough. The inner rim and the outer rim are shown of substantially equal heights and the trough as having a cross-sectionally arcuate bottom which is preferably a sector of a circle. The cutter blades are shown of scimiter form, and their cutting paths are transverse to the trough, their cutting edges cacting with the bottom of the trough for cutting the meat, and the comb acting to arrest a rising tendency of the meat and to coact with the blades for cutting the meat, the infeeding body of meat fed by the rotative action of the trough crowding the meat between and past the knives and past the out-feeding end of the set of blades for again moving with the bowl.

When the material has been properly cut, comminuted or minced, it is ready to be discharged from.v the bowl,V and in the form shown the discharge may be to the inside or to the outside of the trough. When discharged to the inside, it is caused to move through the opening |6| and lbe discharged therefrom into the suitable recep tacle 25.

A scraper |65 is provided for the inner. discharge. It is shown as a strip adjustably secured to the forward face ofthe cover, as by means of bolts |56 passing through enlarged holes in the scraper, and as having a scraper edge |61 coacting with the upper face of the inner rim of the bowl, and an upright scraping edge y|58 coacting with the inner face of the wall of the yopening and .projecting downwardly throughouty sub.-`

stantiall-y the extent of said wall. This structure extends inwardly tangentially to said faces for directing the material through said opening during rotation of the bowl.

If it is desired to discharge the material to the outside of the trough, a discharge spout 1| is provided. This discharge spout has a down- Wardly outwardly sloping shelf |12, end walls |13, |14, and an inner upright securing wall |15, provided with elongatedslots |16 through which bolts |11 extend, the bolts being threaded into the Wall of the housing for clamping the spout in desired position to the frame about the bowl, the slots being perferably wide enough to permit vertical adjustable positioning of the spout (Figs. 1, la, and 8).

IAn adjustable scraper |18 is provided at the inside of the spoutat its out-feeding end to aid in directing the meat into the spout and having a scraper face |19 for scraping 'the upper face of the outer rim of'the bowl and a contact edge 80 for scrapingthe outer peripheral face of said rim. y

The discharge spout has an inwardly extending flange |83 having an inner edge |84 which extends yinto an annular grease groove |85 between the bowl and the frame. This inner edge is of arcuate form having a greater radius than the radius of the arc on which the inner wall |15 is formed, so that the flange tapers inwardly into thev groove from its respective ends toward its middle and has a tendency to push the grease into the groove during rotation of the bowl. Vertical adjustment of the spout causes close contact between the lip and the bowl to prevent mingling between the lubricant and the meat and meat juices. The spout is adjustably securedto the housing in such manner as to adjust it `into desired angular relation to the bowl and to the unloader-employed forfdirecting the meat from the bowl into the spout.

Unloading means are provided for selectively directing the material in the trough inwardly or outwardly, respectively, into the inner discharge or the outer discharge from the bowl. I prefer to employ a rotary unloader for lthe purpose and to selectively rotate the unloader in either of opposite directions for directing the material in the bowl inwardly or outwardly selectively into the respective discharges (Figs. 1, 5, 8, 9 and 11).

Such a rotary unloader is exemplified as a rotating disk v|9|, suitably secured to a hub |92, having a reinforcing backing for said disk, shown as a spider |93 extending from said huband having an annular rim |94 against which the outer portion of the disk issupported. The hub has collars |95, |96 threaded thereon, the disk having a central hole received over said hub and the margin of said hole being clamped between said collars in suitable position lengthwise of the hub, so that the outer vperipheral portion of the disk shall have proper coaction with-said rim |94.

The hub is mounted on a shaft |91, rotating in a tubular portion |98 of apivoted arm |99. The outer end of this arm is provided with a head 200 rigidly secured to the arm and having a bearing 20| thereinfor the outer end of the shaft, the inner end of the shaft being journaled in a bearing 202in the arm and beingprovidedwith a flange 203 bearing against the .inner end of vsaid bearing.

Laterally extending arms 205,206 extend from said head, and at their -outer ends have Scrapers 201, 208 thereon. These. Scrapers are adjustably securedto saidarmsbythreaded studs. 20.9

,asr directed downwardlytoward the trough so that the meat adhering to the unloader -during the unloading action in either direction will be scrapedfrom the unloader. The unloader and Scrapers cause the meat to rise with the ascending side of the unloader and to curl rearwardly withrelation to the direction of the rotation of the trough, and laterally, inward or outward, depending on the direction of rotation of the unloader, to direct the flow of meat over the inner or outer rim of the trough, either for inward-discharge or for outwarddischarge therev of at the unloading station at which said unlloaderis located, for discharging inwardly over ses.

the inner rim at the inner portion of such stationor over the outer rim and the outwardly slopingfshelf H2 at the outer portion of such station.l f

The hub EQ2 is clamped against the outer end ,ofA the inner raceway of the bearing 2M by a clamping nut A2M and a jam nut 2l5 over a 'threaded reduced outer portion of said shaft,

to locate said bearing.

The shaft is provided with an outer reduced end 2id about which there is a handle 220 positicned endwise by ay locating pin 22E threaded in said handle in countersunk relation and having an inner end received in an annular groove 223 in said reducedend of said shaft. The handle is rotatively loose about the shaft, so that thehandle may be grasped by the hand for manipulating the unloader.

lAn unloader bracket 225 is secured to the housing 22. It is `provided with pivot bearings 226. The unloader frame has a depending bracket portion 221 in which there are bearings Av pivot rod 228 is located in said bearings, being fixed tothe bearings of the unload-er arrn so-asto rotate with the pivotal movements of the unloader (Figs, 1, 8 and `14). l

The bracket 225 is provided with extensions 23d shown as slanting downwardly and outwardly and havingadjustable stops 23! therein, shown as vbolts adjustable in threaded holes in said extensions, and provided with jam nuts 232 for holding the bolts in adjusted positions. f The depending portion 221 is provided with a shelf l235 for supporting a suitable reversible electric motor 235 in conjunction' with which there'is suitable reducing gearing 237 shown in tandem with the motor in the present exemplication, the delivery end of the motive mechanism having a shaft 238, between which and the unloader shaft there is a suitable coupling 239 for transmitting the rotations of the rotor in either direction to the unloader shaft.

A suitable switch box 26H is provided and contains suitable mechanism for controlling the direction fof rotation of the unloader motor and the starting and stopping of the same (Figs. 1, 8 and' 10). Thus a suitable reversing switch 242 isprovidedior controlling the direction of rotation of the motor, and consequently the direction of rotation of the unloader for inward or outward discharge of material from the trough. A normally closed electric switch 243 is provided for controlling the operation of the motor. The pivot rod of the unloader arm has a control arm 244 secured thereto, which moves with the movement of the unloader arm. When the unloader is in rais-ed position, this control arm contacts the button 245 of the control switch 243 for opening said switch throughout the time that the unloader is raised. When the unloader is depressed into the trough, the control arm moves away from the button of the control switch for permitting the latter to close and thereby complete the circuit for the unloader motor, either through its forward or reverse rotation contacts in the reversing switch, as the same may be manipulated, for controlling the fact of rotation and the direction of rotation of the unloader. Rotation begins substantially when depressing of the arm begins, so that disk is at full speed upon contact with the meat, providing for a delayed full speed and full power operation of the electric motor between the time vof the electric motor upon contact of the disk with the meat in the trough, thereby providing for acceleration of rotation in the motor and of said disk for full power actuation of the unloading disk upon entry thereof into the trough.

The unloader arm and its parts are so related that there is an overbalancing of the motor arm into release relation. The rotary unloader is shown at one end of said arm, and the electric motor for driving the same is located at the other end of said arm, with the pivot for said arm between the same, the motor end of the arm overbalancing the unload-er end of the arm and causing the unloader to normally rise out of the trough. The adjustable stop 23! is provided for adjustably stopping the automatic movement of the unloader arm into retracted position with the control arm 26d thereof properly operating the control switch M3,

There is an anti-friction device between the supplemental frame and the bowl, shown as a raceway on the supplemental frame, having a lower substantially horizontal face 2d@ and an outer upright face 256 (Figs. and 8b). The opposing raceway is on the bowl, and comprises an upper substantially horizontal face 25| and an inner 4depending face 252, which is substantially upright. These faces are annular. Balls 253 are located between said raceways, and rotatively support the bowl on said supplemental frame. The manners in which the faces of these raceways are directed are especially beneficial by providing substantially horizontal supporting faces for the anti-friction elements receiving the vertical stresses on the bowl and substantially vertical opposing annular faces receiving the horizontal stresses on the bowl, and for rotating the balls on axes which are radial and converging with relation to ,each other, converging below the bowl and toward the axis of rotation of the bowl, thus locating said axes in a conical plane.

The frame is provided with an upwardly extending annular tongue 256, and the bowl is provided with a downwardly opening annular groove 251, the walls of which are received about the tongue, there being lateral spaces 258, 259

between the tongue and said walls, and the upper edge of the tongue being spaced, as by the annular space 28|),V from the bottom of said groove, adjustments for maintaining such spaced relations being provided by means hereinafter described. An upper lubricating slot and lateral lubricating slots are thereby provided between the tongue and the walls of the groove, and these lubricating slots may be enlarged by grooves 25|, located annularly in one or more of the walls of said slots, being shown located opposite each other in the tongue and in the outer depending wall 262 of the groove. The oppositely located grease grooves aid in forming a grease seal between the housing and the bowl, the grease filling said grooves and the space therebetween (Figs. 1a, 5 and 7).

Lubricant channels 263 communicate with said lubricating slots, being shown located in the tongues and having outer threaded branches` 264 in which suitable lubricant nipples 265 are secured, and through which lubricants may be forced by any suitable force feeding means, so as to supply a lubricant into said slots, the lubricant being preferably a heavy grease. The mouths 256 of the lubricating slots preferably discharge into the upper annular slot 260. The lower ends of said side slots 258, 259 may be provided with oppositely opening annular mouths |85, 268, the walls of which are located respectively as shoulders on the said housing at the base of said tongue and as shoulders on said bowl at the lower ends ofthe lateral walls of said slots.

A lubricant channel 269 (Fig. 8b) communicateswith the friction reducing bearing between the supplemental frame 28 and the bowl, its feedin mouth being shown as discharging into the lower raceway thereof. A feed pipe 210 for the lubricant, such as grease, extends therefrom through an enlarged hole 210a in the inwardly extending flange of the housing 22, and is` provided with a lubricant feed nipple 2101i.

The tapering flange or lip |83 of the discharge spout may extend slightly into said outer annular mouth or grease groove |85, and is positioned against the upper wall of said mouth on the bowl forforming a tight joint with said bowl (Figs. l, la and 8), this construction aiding in maintaining the grease within the groove |85 and p.eventing its leaking down the outer periphery ,f the housing 22, and preventing intermingling between the meat and the meat juices and the ubricant, as hereinbefore explained.

Adjustments are provided for the supplemental frame for adjusting the bowl vertically with relation to the cutting paths of the knives, and for locating the rims of the bowl into close connection with the cover so as to form close joint therewith and prevent escape of meat and meat juices from the bowl, and for proper relation between the lubricant passages at the tongue and groove connections between the bowl and the frame. Radial adjustments are also provided for said supplemental frame for adjusting the axis of rotation of the bowl for aiding in proper drive relation between the worm and the worm wheel and proper lateral positioning of the bowl at the lubricating passages between it and the frame and for proper cutting relation between the: cutting paths of the blades and the trough.

Vertical adjustment is provided for the supplemental frame by means of adjusting bolts 21| passing through enlarged holes 212 in the flanges 213 of the respective legsr of the main frame and threaded into the lower inwardly extending'rangeof thehousing of the main frame (Figs. 5 and 8), the upper ends of the bolts being received in recesses 214 of greater diameter than the diameter of the upper ends of said bolts for permitting radial adjustment of said supplemen tal frame. Each of the bolts is provided with a jam nut 215 for holding the bolt in adjusted position.

The depending flange 216 of the supplemental frame has adjusting bolts 211 threaded therein, arranged to Contact the inner edge'of the lower inwardly extending Iiange of the housing of the main frame and thereby adjusting said supple-` mental frame radially and in lateral directions with relation to the main frame for adjusting the axis of rotation of the bowl. Each of these adjusting bolts is provided with a jam nut 218 for holding the same in adjusted positions.

The vertical and horizontal adjusting means may be each three in number, equally distanced about the circumference of the supplemental frame for making three point adjustments in each case.

The depending wall 262vdirects any meat juices from the bowl downwardly past the grease groove |85 (Figs. 5, 7 and 8b), and the depending flange 21S overlaps the inner end of the lower flange of the housing 22 to form an interrupting joint 280 to arrest the passage of hot flushing water under pressure into the annular'space 28| between the housing 22, the supplemental frame 28 and the bowl, the lapping joint 282 formed between the depending ange 283 of the bowl and the upper inner periphery of the supplemental frame arresting the passage of such hot flushing water into said annular space and to the grease imbedded ball bearing between the bowl and the supplemental frame. This ball bearing forms a grease joint which acts in conjunction with the grease joint between the tongue 255 and the groove 251 in maintaining said annular space 28| clean.

'Ihe inner opening i6! maybe temporarily closed (Figs. 5a and 8a) by a removable closure 285 while charging the bowl with meat tobe cut, to prevent such uncuty meat from dropping through said inner opening. The closure may rest on the upper endof the wall of the inner opening |6l, and be provided with a handle 281 for manipulating the same. Any charged meat which may drop on the closure may be wiped by a suitable knife or blade into the trough. The closure is removed before starting the cutting operation of the machine.

In operation, the bowl is rotatable inthe main frame and has an annular material trough in which a set of rotary cutters rotate with cutting paths which are transverse to said trough. The axes of rotation for the driving means for the bowl and the cutter are all located above the horizontal plane in which thelower end of the bowl is located, and an electric motor is adjustably mounted on a cover covering the rear portion of the bowl, so as to provide proper tension to flexible driving connections between the motor and `the cutter shaft, and at the same time they frame is so constructed that a material receptacle may be rolled or otherwise positioned under the middle of the bowl for receiving material discharged inwardly from the trough of the bowl, or the receptacle may be placed at the outer rim of the bowl for receiving material discharged outwardly from the chute.

Both vertically and horizontally acting adjustingr means of novel and extremely 1 simple,

the infeeding end of the set of cutters, insuring movement of the material itno the iield of action ofthe cutters and feeding movement of the meat by the bowl past the cutters, accomplished specifically by movement of an infeeding tongue at the infeeding end of the comb coacting with the cutter blades. Unloading means are provided for the cut c comminuted meat in the bowl, either selectively inwardly or outwardly, a rotary unloader comprising a rearwardly dish-shaped unloading .disk being provided and'having means in connection therewith for rotatingvin either -of opposite directions fordischarging'` 'the material in the trough inwardlyor outwardly as the trough is rotating, the operation of said rotary unloader f. being automatically controlled by its active and retracted positions, as by providing an automatically controlled switch for an electric motor for rotating the unloader.

'I'he unloader is furthermounted on an overbalanced arm, so that the unloader is automatically retracted into inactive position, and when so retracted having its rotations stopped, the pivot of the unloader frame being located between the unloader at one end thereof and the electric "1 motor for voperating the same at the other end thereof.

Novel means are also provided for centrally locating the bowl for proper coaction between the various operating parts and the bowl, and the bowl is also mounted on anti-friction bearing rvmeans, ther resistances to stresses in which -are vertical to resist the bearing and weight stresses of thek bowl, and horizontal toresist the driving and shifting stresses of the bowl. Y In my improved device the outer discharge and the inner discharge'may be provided for different charactersof meat. The cutting operation takesplace rapidly in my improved device, in fact, more rapidly than the time consumed by subsequent operating steps yupon the meat. For instance,

the mixing operation on the cut meat is substantiallyv slower than the cutting operation. The outer discharge may therefore be arranged for delivery into a suitable mixing machine, and interv mediate batches of meat of other characters may be cut during the mixing of the first-named batch and discharged through the inner discharge of my improved device for other subsequent operations thereon, so that my improved rdevice may 'z be substantially continuously employed.

My improved construction provides a compact and simple mechanism in which the parts are associated in economical manner for structure and assembly, and in which the operative devices are placed for most economical and convenient service, provides a construction in which the meat isr free from human contact, and in which the discharge may take place either inwardly or outwardly with relation to the trough.
